Default Solution NMR Spectroscopy for the Study of Enzyme Allostery.

Solution NMR Spectroscopy for the Study of Enzyme Allostery.

Chem Rev. 2016 Jan 6;

Authors: Lisi GP, Loria JP

Abstract
Allostery is a ubiquitous biological regulatory process in which distant binding sites within a protein or enzyme are functionally and thermodynamically coupled. Allosteric interactions play essential roles in many enzymological mechanisms, often facilitating formation of enzyme-substrate complexes and/or product release. Thus, elucidating the forces that drive allostery is critical to understanding the complex transformations of biomolecules. Currently, a number of models exist to describe allosteric behavior, taking into account energetics as well as conformational rearrangements and fluctuations. In the following Review, we discuss the use of solution NMR techniques designed to probe allosteric mechanisms in enzymes. NMR spectroscopy is unequaled in its ability to detect structural and dynamical changes in biomolecules, and the case studies presented herein demonstrate the range of insights to be gained from this valuable method. We also provide a detailed technical discussion of several specialized NMR experiments that are ideally suited for the study of enzymatic allostery.

J Phys Chem B. 2013 Feb 26; Authors: Manley GA, Rivalta I, Loria JP Abstract Allosterism is an essential biological regulatory mechanism. In enzymes, allosteric regulation results in an activation or inhibition of catalytic turnover. The mechanisms by which this is accomplished are unclear and vary significantly depending on the enzyme. It is commonly the case that a metabolite binds to...

NMR post-doc position: NMR-based dynamics study of enzyme mechanism
The following post-doc position in NMR is available in University of Missouri: Ad text: """ We have an opening for a postdoctoral fellow to use NMR to study dynamics of an enzyme while it is carrying on reversible catalysis. The prospects are promising and can be compared with thorough enzymology and crystallography of its ligand-dependent conformational changes (done in our dept.). The enzyme is sizeable enough to be challenging, but we have a battery of excellent 800 MHz spectra of deuterated samples for launching the project. The postdoctoral fellow will be housed in a new...
